PURPOSE This study aimed to evaluate the use of stone density variation coefficient (SDVC) as an indicator of stone heterogeneity and previously reported parameters for predicting extracorporeal shock wave lithotripsy (ESWL) outcome in urinary calculi. Moreover, a new formula that could be used to predict ESWL success was suggested. METHODS A total of 850 patients, who underwent the first session of ESWL for urinary stones between 2015 and 2020, were examined, and 220 eligible patients were included in the study. Read More

Complex biliary stones may be challenging to remove with standard endoscopic techniques. Factors contributing to complexity include large stone size (≥15 mm), multiple stones, high stone:distal duct ratio, stones above strictures and those in difficult anatomic position. In these cases, additional techniques may be needed, such as endoscopic papillary large balloon dilatation, mechanical lithotripsy, cholangioscopic visually directed lithotripsy, and extracorporeal shockwave lithotripsy.

Objectives: To demonstrate the efficacy and cost-effectiveness of acute extracorporeal shockwave lithotripsy (ESWL) for ureteric stones we present our experience of ESWL in 530 ureteric stone cases, in the largest UK series we are aware of to date. ESWL is underutilised in ureteric stone management. The Getting It Right First Time (GIRFT) report showed just four units nationally treated >10% of acute ureteric stones with ESWL. Read More

Purpose Of Review: The aim of this study was to discuss current trends and recent developments in the surgical management of paediatric urolithiasis.

Recent Findings: Medical expulsive therapy (MET) is considered as an option for the treatment of children with ureter stones. Extracorporeal shockwave lithotripsy (SWL) remains as a first option for majority of kidney stones and upper ureter stones. Read More

Shock waves are commonly used in the field of urology. They have two phases, positive and negative, and the bubble generation is roughly classified into acoustic cavitation (AC) and laser-induced cavitation (LIC). We evaluated the occurrence of cavitation, its duration, the area of interest, and the maximal diameter of the cavitation bubbles. Read More

This article aimed to review the clinical application and evidence of the therapeutic ultrasound in detail for urological diseases such as prostate cancer, kidney tumor, erectile dysfunction, and urolithiasis. We searched for articles about high-intensity focused ultrasound (HIFU), extracorporeal shock wave therapy, ultrasound lithotripsy, and extracorporeal shockwave lithotripsy (ESWL) in the MEDLINE and Embase. HIFU may be indicated as a primary treatment for low- or intermediate-risk prostate cancer, and salvage therapy for local recurrence as a promising way to address the limitations of current standard therapies.

Objective: Artificial neural networks (ANNs) are widely applied in medicine, since they substantially increase the sensitivity and specificity of the diagnosis, classification, and the prognosis of a medical condition. In this study, we constructed an ANN to evaluate several parameters of extracorporeal shockwave lithotripsy (ESWL), such as the outcome and safety of the procedure.

Methods: Patients with urinary lithiasis suitable for ESWL treatment were enrolled. Read More

Objective: To evaluate the efficacy of extracorporeal shockwave lithotripsy (ESWL) in supine trans-abdominal approach for distal ureteric calculi and to determine the variables that could affect the outcome results.

Materials And Methods: Between November 2019 and January 2021, 172 patients with a solitary distal ureteric calculus were treated with ESWL in supine position with a pronated shock wave head against the anterior abdominal wall. The outcome of treatment evaluated and the clinical and radiological findings, as well as stone characteristics, were reviewed and correlated with the stone-free rate (SFR). Read More

Background Nephrolithiasis is one of the most common renal pathologies and is routinely encountered in daily practice. Non-contrast computed tomography (NCCT) is the gold standard diagnostic imaging modality for urolithiasis. The role of HU (Hounsfield units) in calculus as a predictor of extracorporeal shock wave lithotripsy (ESWL) has been studied in the past. Read More

From 1988 to 2018, ESWL therapy was performed with 3 successive types of lithotripters in our hospital. From 1988 to 1998, the electrohydraulic lithotripter NS-15 was used, and the electromagnetic lithotripter HK-V was put to use in 1999. Read More

Purpose: Although extracorporeal shockwave lithotripsy (SWL) has been confirmed to be effective in treating ureteral stone, a definitive conclusion on which patient's position is the optimal option during SWL treatment remains unclear. We, therefore, performed this updated meta-analysis to further clarify it.

There is very little published literature on urologic diseases prior to 1947 from areas now constituting Pakistan. From inception of the country to 1970s, urology was part of surgery practiced by general surgeons except for two urology units established in 1960s. The real take off of urology began with introduction of transurethral resection of prostate (TURP) in 1980s, ushering the era of endourology; the second era of which began with ureteroscopy along with extracorporeal shockwave lithotripsy (ESWL) in 1987-1989, percutaneous nephrolithotomy in 1992 and introduction of percutaneous nephrostomy in 1997.

Purpose: Comparisons of ureteroscopy (URS), extracorporeal shockwave lithotripsy (SWL), and percutaneous nephrolithotomy (PCNL) for urolithiasis considering long-term health and economic outcomes based on claims data are rare. Our aim was to analyze URS, SWL, and PCNL regarding complications within 30 days, re-intervention, healthcare costs, and sick leave days within 12 months, and to investigate inpatient and outpatient SWL treatment as the latter was introduced in Germany in 2011.

Methods: This retrospective cohort study based on German health insurance claims data included 164,203 urolithiasis cases in 2008-2016. Read More

Background: Today, the most common method for kidney stone therapy is extracorporeal shock wave lithotripsy. Current research is a numerical simulation of kidney stone fragmentation via ultrasonic shock waves. Most numerical studies in lithotripsy have been carried out using the elasticity or energy method and neglected the dissipation phenomenon. Read More

The burden of kidney stone disease has risen, and several treatment options now exist. We wanted to evaluate the preference and treatment choices based on the information provided for management of hypothetical 8 and 15 mm renal stone, and factors that influenced their decision. An online questionnaire to investigate trends in decision-making for two hypothesized scenarios of asymptomatic kidney stones (8 and 15 mm) was formatted online in Microsoft Forms and posted on social media (Facebook) in Europe.
